Typical urine drug tests for employment purposes usually screen for 5 to 10 drugs. The immunoassay is performed first and is often used as a screening method. If the immunoassay is negative, no further action is required, and the results are reported as negative.

These factors change based on exposure to medication, certain foods, diseases, and other factors.

A confirmatory test should always be conducted before reporting a positive test result to ensure accuracy. If the results are positive or inconclusive, a confirmation test, called a confirmatory GC-MS analysis, may be conducted on a separate part of the same biological sample. The person starts urinating and collects urine in the collection cup during the middle of their urine stream. They then close the container with the lid and give the sample to the test administrator.

Blood Drug Tests

Negative tests are returned faster than positive because of the need for follow-up testing after a positive result. But urine tests can detect a wider range of substances and work faster. The former produces more false positive and false negative results than the latter.

Random drug screening may be used in instances of workplace accidents, and if the employer has suspicion that the employee is abusing drugs. Random drug testing may occur without cause for suspicion depending upon company policy.

This is a routine drug detection test where the biological specimen you submit (urine, saliva, etc.) is tested for the presence of drugs. Like a breath test (breathalyzer test), this process is quite common and detects your blood alcohol concentration (BAC). How long alcohol stays in urine can vary depending on many factors, but it can typically be detected between 24 and 72 hours. Testing in this manner is very accurate, fast, and easily accessible through lab testing and at-home kits.
